Tarsal Tunnel Syndrome Rehabilitation Exercises

At a glance: Tarsal tunnel syndrome is compression of the posterior tibial nerve as it passes through a narrow channel (the tarsal tunnel) behind the inner ankle bone. The symptoms — burning, tingling, numbness, and shooting pain into the arch or toes — are very similar to carpal tunnel syndrome in the wrist. It can be caused by anything that takes up space in the tunnel: swelling from a sprain, a ganglion cyst, varicose veins, flat feet stretching the nerve, or systemic conditions like diabetes or thyroid disease.

Understanding Tarsal Tunnel Syndrome

The tarsal tunnel is formed by the flexor retinaculum — a band of connective tissue — stretched over the posterior tibial nerve, artery, and vein as they pass behind the medial malleolus (inner ankle bone). Within this tunnel, the posterior tibial nerve divides into the medial and lateral plantar nerves, which provide sensation to the bottom of the foot. When the tunnel contents are compressed, the nerve can't function properly, producing the characteristic burning, tingling, and numbness. The nerve gliding exercises in this program help the nerve move freely within the tunnel and reduce adhesions that develop from chronic compression.

Common Symptoms

Burning, tingling, or electric sensations along the inner ankle, arch, or sole
Numbness in the bottom of the foot or toes
Pain that worsens with prolonged standing or walking
Symptoms that are worse at the end of the day
Shooting pain that radiates from the inner ankle into the foot
Tapping behind the inner ankle reproduces the symptoms (Tinel's sign)

The Walking Self-Test

Before you begin any exercises, this simple self-test shows you what your feet are actually doing when you walk. Most of us have no idea — we just walk. But your feet may have quietly developed blind spots: parts of the sole that don't engage anymore, toes that don't push off, or an arch that has checked out. This test takes 60 seconds and gives you a personal baseline you can revisit after each week of exercises to feel your progress.

How to do it: Take off your shoes and socks. Walk slowly across a room — about 10 steps. Pay close attention to each step and notice: Does your heel land first, or does your whole foot slap down at once? As your weight moves forward, do you feel it roll through your arch? Do all five toes engage and push off at the end of the step, or do some of them just ride along? Is one foot doing more work than the other? Don't try to "fix" anything — just notice. That awareness is the starting point. Repeat this test after one week of doing your exercises. Most patients are surprised by how much they can feel changing.

Do this before your very first exercise session, then repeat it once a week. It's your personal progress tracker — no equipment, no numbers, just awareness. Many patients tell us this simple test was the moment they realized their feet weren't working the way they thought.

How to Monitor Pain During Exercise

Use a 0–10 scale to rate your pain during exercise, where 0 is no pain and 10 is the worst imaginable.

🟢 0–3: You're in the clear. This level of mild discomfort is normal and safe.

🟡 4–5: Proceed with caution. Reduce the number of reps or don't push as far into the stretch.

🔴 Above 5: Stop the exercise. Go back to the easier tier and try again in a day or two.

Which Level Should I Start At?

Mild — "It bothers me, but I can get through my day"

Pain ≤3 out of 10 at rest. You're walking normally. Daily activities are manageable with minor discomfort.

Moderate — "It's changing how I move"

Pain 4–6 out of 10. You might be limping or avoiding certain activities. Some things you used to do easily are now uncomfortable.

Severe — "It's hard to put weight on it"

Pain 7+ out of 10. Walking is difficult. You may need to hold onto furniture or avoid standing altogether.

Start With These Exercises

Wall Calf Stretch — Gastrocnemius (Straight Knee)

This stretch targets the gastrocnemius — the big, powerful calf muscle that gives your leg its shape. It crosses both the knee and the ankle, which is why you stretch it with a straight knee. When this muscle is tight (a condition called equinus), it forces the front of your foot to work overtime with every step, contributing to heel pain, bunions, metatarsalgia, Achilles problems, and more. Loosening it up is one of the single most impactful things you can do for your feet.

What to expect: You should feel a noticeable difference in ankle flexibility within 2–4 weeks of daily stretching. Many patients report that heel pain and forefoot pressure begin to ease as the calf loosens. The clinical goal is at least 10 degrees of ankle dorsiflexion (the ability to pull your foot up toward your shin) — your podiatrist can measure this at your visit.

How to do it: Stand facing a wall with your hands flat at shoulder height. Step one foot back about 2 feet. Keep the back knee STRAIGHT and the heel firmly on the ground — this is the key. Lean gently into the wall until you feel a good stretch in the upper calf of the back leg. Keep your toes pointed forward, not turned out.

Level	Hold	Reps	Sets	How Often	Tips
Mild	30 sec	3	1	3×/day	That's 90 seconds per leg, per session. It should feel like a firm, satisfying stretch — not pain
Moderate	30 sec	2	1	2×/day	Don't lean as far into the wall if the stretch is uncomfortable. Heel stays down no matter what
Severe	20 sec	2	1	1×/day	If standing is too much, try the seated version: sit with your leg out, loop a towel around the ball of your foot, and gently pull your foot toward you

How to progress: Increase hold time to 45–60 seconds. Try slight toe-in and toe-out angles to stretch different parts of the muscle. Eventually, you can do this on a slant board for a deeper stretch.

⚠ When to skip this: Do not do this if you suspect an Achilles rupture (a sudden pop or snap in the calf). If you have insertional Achilles tendinopathy (pain right where the tendon meets the heel bone), do NOT stretch past neutral — stop before you feel the heel stretch. DVT (blood clot) suspicion: if your calf is swollen, red, and warm, see a doctor immediately instead of stretching.

Wall Calf Stretch — Soleus (Bent Knee)

This is the partner stretch to the one above. The soleus is the deeper, flatter calf muscle that sits underneath the gastrocnemius. Because it only crosses the ankle (not the knee), you have to bend the knee to isolate it. It's a workhorse muscle — responsible for much of your standing endurance and push-off power when walking. Tightness here directly limits how far your ankle can bend, which cascades into problems throughout the foot.

What to expect: When the soleus loosens up, patients typically notice easier walking on inclines, less ankle stiffness after sitting, and improved squat depth. Combined with the gastroc stretch above, you're addressing the #1 biomechanical problem we see in the office: tight calves.

How to do it: Same wall position as above, but this time BEND the back knee while keeping the heel glued to the ground. The stretch will feel different — lower and deeper, closer to the ankle rather than high in the calf. That's exactly what you want.

Level	Hold	Reps	Sets	How Often	Tips
Mild	30 sec	3	1	3×/day	Always do this AFTER the straight-knee stretch — gastroc first, then soleus
Moderate	30 sec	2	1	2×/day	Bend the knee more to deepen the stretch, less to lighten it — you're in control
Severe	20 sec	2	1	1×/day	Seated option: sit with your knee bent, foot flat on the floor, and gently push your knee forward over your toes while keeping the heel down

How to progress: Work up to 45–60 second holds. Try single-leg soleus stretches on a step: stand on the edge with the heel hanging off, bend the knee, and let the heel drop gently below the step.

⚠ When to skip this: Same as the straight-knee stretch: avoid with suspected Achilles rupture, and limit the range for insertional Achilles tendinopathy (don't push the heel below neutral).

Towel Curl

This exercise strengthens the small muscles on the bottom of your foot — called the intrinsic foot muscles. These are the muscles that support your arch from the inside, kind of like a built-in orthotic. When they're strong, they help distribute your body weight more evenly, protect against overpronation (your foot rolling inward too much), and take stress off the plantar fascia, tendons, and joints.

What to expect: You may not feel dramatic changes in the first few weeks, but stick with it — these small muscles take time to build. By 6–8 weeks, many patients notice better arch support, less foot fatigue at the end of the day, and improved balance. The research shows measurable strength gains by 4–6 weeks.

How to do it: Sit in a chair with your bare feet flat on the floor. Lay a small towel flat under your foot. Curl your toes to scrunch the towel toward you — like you're trying to pick it up with your toes — then spread your toes flat and repeat. Try to use all five toes, not just the big one.

Level	Hold	Reps	Sets	How Often	Tips
Mild	3–5 sec per curl	10	3	1×/day	Focus on curling with all your toes evenly — it takes practice, and that's okay
Moderate	3 sec per curl	8	2	1×/day	Use a thin towel on a smooth floor to make it easier
Severe	2 sec per curl	5	1	1×/day	If the towel is too hard, just practice curling your toes on carpet without it

How to progress: Start with a thin towel on a smooth floor → thicker towel → place a small water bottle at the far end of the towel for added resistance. When seated feels easy, try it standing.

⚠ When to skip this: Hold off if you're recovering from hammertoe surgery or an acute plantar plate tear (first 4 weeks). Your surgeon will let you know when it's safe to start.

Half-Kneeling Dorsiflexion Mobilization

This mobilization targets the ankle joint itself — specifically the talocrural joint, where your shin bone meets your foot. Sometimes ankle stiffness isn't just tight muscles; the joint capsule itself gets stiff, especially after injury or immobilization. This exercise gently pushes the talus bone (your ankle bone) backward in its socket while improving dorsiflexion (the ability to bend your ankle upward). Think of it as "oiling" the hinge of a stiff door.

What to expect: You should notice improved ankle "bend" within 1–2 weeks. A simple home test: kneel in front of a wall, put your toes 4 inches from the wall, and try to touch your knee to the wall without lifting your heel. Track your progress by increasing the distance — 5 inches is good, 6+ inches is great.

How to do it: Kneel on one knee (a folded towel under the knee helps). Place the other foot flat on the floor in front of you. Keep that front heel firmly on the ground and gently drive the front knee forward over your toes — your knee should track over your 2nd or 3rd toe. You'll feel a deep stretch in the front of the ankle.

Level	Hold	Reps	Sets	How Often	Tips
Mild	5-sec oscillations or 30 sec sustained	15	3	1×/day	Oscillate: gentle rhythmic push-and-release at end range. Like rocking a stiff door open a little further each time
Moderate	5-sec oscillations	10	2	1×/day	Smaller range of motion — don't force it to end range. Stop immediately if you feel pinching in the front of the ankle
Severe	gentle oscillations only	8	1	every other day	Try the seated version: sit with your foot flat on the floor and gently lean your knee forward over your toes. Skip this if the ankle is still swollen

How to progress: Increase the depth of the lunge. Add a resistance band looped around the ankle (pulling backward) for a posterior glide mobilization — this gives the joint a mechanical advantage. Measure progress with the knee-to-wall test.

⚠ When to skip this: Skip with an acute ankle fracture. If you have a bone spur at the front of the ankle (anterior impingement), this may cause pinching — stop if you feel a sharp catch in the front of the joint. Wait for post-surgical clearance.

When to See Dr. Patish

Nerve symptoms in the foot should always be evaluated to rule out more serious causes. Dr. Patish can perform a Tinel's test, assess for contributing factors (flat feet, swelling, cysts), and determine whether conservative treatment (orthotics, nerve gliding exercises, injections) or further workup (nerve conduction studies) is needed.

Frequently Asked Questions

Is tarsal tunnel syndrome like carpal tunnel?

Very similar concept — both involve a nerve compressed in a tunnel formed by bone and a retinaculum. The main difference is that tarsal tunnel syndrome is much less common and often harder to diagnose because foot numbness gets attributed to other causes (neuropathy, plantar fasciitis).
